Potential energy since the energy is being stored and not in use
Answer: 896J
Explanation:
Given that
Mass of motorcycle = 112kg
kinetic energy = ?
velocity of the motorcycle = 4m/s
Since kinetic energy is the energy possessed by a moving object, and it depends on the mass (m) of the object and the velocity (v) by which it moves. Therefore, the motorcycle has kinetic energy
i.e K.E = 1/2mv^2
KE = 1/2 x 112kg x (4m/s)^2
KE = 0.5 x 112 x 16
KE = 896J
Thus, the motorcycle has 896 joules of kinetic energy.
Answer:
The magnitude of the magnetic torque on the coil is 1.98 A.m²
Explanation:
Magnitude of magnetic torque in a flat circular coil is given as;
τ = NIASinθ
where;
N is the number of turns of the coil
I is the current in the coil
A is the area of the coil
θ is the angle of inclination of the coil and magnetic field
Given'
Number of turns, N = 200
Current, I = 7.0 A
Angle of inclination, θ = 30°
Diameter, d = 6 cm = 0.06 m
A = πd²/4 = π(0.06)²/4 = 0.002828 m²
τ = NIASinθ
τ = 200 x 7 x 0.002828 x Sin30
τ = 1.98 A.m²
Therefore, the magnitude of the magnetic torque on the coil is 1.98 A.m²
Answer:
Reflection is when light bounces off an object, while refraction is when light bends while passing through an object.
